Psalms 14:7

"Oh that the salvation of Israel were come out of Zion!

When Jehovah bringeth back the captivity of the people.

Then shall Jacob rejoice, and Israel shall be glad."

One of the best comments on this we have seen is that of Addis:

Here is the Messianic hope. The Psalmist anticipates a time when Yahweh will "bring back the captivity" of His people. This expression need mean no more than a radical change for the better in the state of the people. "Restore the fortune" would be an adequate translation.[10]

"There is no need to refer the expression `bringeth back the captivity' to the Babylonian exile."[11] The expression here has the same meaning that it has in Job 42:10. namely, "restoring prosperity to."

Jacob and Israel here are names that refer to the people of God.

The appearance of this Messianic promise at the end of this prophesy of the third total depravity of the race of Adam (When this was written there had already been two such hardenings.) has the utility of revealing this Psalms 14, and its twin Psalms 53, as a double prophecy of the Third Judicial Hardening of Adam's race and God's response to it in the First Advent of the Lord Jesus Christ, bringing life and immortality to light through the gospel, and ushering in the dispensation of Christianity. This is "God's last word to man." "Last of all, God sent his Son" (Matthew 21:37). When, once more, Satan is able to accomplish through the indifference and wickedness of mankind another situation of total hardening and depravity, our rebellious race may indeed expect the final Judgment of the Great Day.
